<p><em>High genetic diversity is one factor that determines the success of plant breeding. Mutation induction by gamma ray irradiation is one method to improve plant genetic diversity. This study aimed to 1) obtain growth regulators composition suitable in inducing embryogenic callus, 2) determine the effect of gamma ray irradiation on the growth and development of somatic embryos, and 3) obtain lethal dose (LD) <sub>20</sub> and <sub>50</sub> values in Robusta coffee  BP 436. The study was conducted at the Tissue Culture Laboratory, Industrial and Beverage Crops Research Institute,  from May 2017 to December 2018. Explants used were young leaves of Robusta coffee BP 436. Callus induction used ½ MS media with 2,4-D (4.52 μM) and 2-iP (0.00; 4.93; 9.86; 14.79; and 19.72 μM) treatment. Mutation induction was performed using gamma radiation dosed at 0, 10, 20, 30, 40, and 50 Gy treatments. The regeneration media was ½ MS containing GA<sub>3</sub> (0 and 1 mg/l). The study used a complete randomized design with 10 replications. The results showed the best combination of plant growth regulator to induce the callus was 2.4-D 4.52 μM + 2-iP 19.72 μM. The fresh weight of cultures was inhibited above 30 Gy, whereas the number of somatic embryos decreased at doses above 10 Gy. Addition of GA<sub>3</sub> 1 mg/l in regeneration media increased the number of somatic embryos in torpedo phase, but not in gamma irradiation exposed calluses. The LD<sub>20</sub> and LD<sub>50</sub> of Robusta coffee BP 436 are 16.81 and 28.52 Gy, respectively.</em></p>

Effect of gamma irradiation [60Co] against Bactrocera carambolae Drew & Hancock in vitro and in vivo. Bactrocera carambolae Drew & Hancock is one of the most important pests on guava fruit. According to a quarantine regulation in export-import commodities, irradiation treatment is a suitable methods for eradicating infested organism, which is relatively safe for the environment. The aim of this research was to determine mortality doses and an effective dose of [60Co] gamma ray irradiation for the eradication purpose, and its implication on the survival of fruit fly B. carambolae. Two irradiation methods of in vitro dan in vivo were carried out, by exposing egg and 3rd instar larvae of B. carambolae obtained from the laboratory reared insect. Eleven doses of gamma ray irradiation of 0, 30, 50, 75, 100, 125, 150, 175, 200, 300, 450, and 600 Gy were applied, respectively. The level of 99% fruit fly mortality was estimated by the value of LD99 using probit analysis and the number of larvae, pupae and adult survival were evaluated by analysis of variance (ANOVA), and the means compared by Tukey’s test, at 5% of significance level. These result showed that the effective lethal dose (LD99) of irradiation that could be successful to eradicate eggs and 3rd instar larvae in vitro were 2225 and 2343 Gy and in vivo were 3165 dan 3177 Gy, respectively. Almost all of the treated larvae survived and developed to pupae, therefore only the minimum irradiation dose of 30 Gy allowed the pupae to develop into adults.

Winged bean [Psophocarpus tetragonolobus (L.) DC] is a tropical plant that has some benefits and is very suitable to be cultivated in Indonesia. Study about diversity of winged bean is very important to support the future development of winged bean. Increased genetic diversity can be done through mutation. Gamma ray is often used for inducting mutations. One of way to observe genetic diversity resulted by molecular mutation is using RAPD method. The purpose of this study was to identify the genetic diversity of winged bean resulted by gamma ray irradiation. The method used in this study was an experiment by using RAPD technique. Samples used were plant leaves that had been induced by gamma ray with a wavelength of 20 Gy, 25 Gy, and control plants that were not induced by gamma ray. RAPD were done by ten primers that were OPA 9, OPA 10, OPA 13, OPA 18, OPB 2, 3 OPB, OPB 6, 7 OPB, OPB 10, and OPB 11. Data were analyzed using GenAlex 6.1 Program. The percentage of polymorphic loci of winged bean population control was 47,54%, while in the 20 and 25 Gy treatment were 62,30% and 54,10%, respectively. The values of genetic variation based on the calculation of allele frequencies were 0,236; 0,202 and 0,194 for treatment of 20 Gy, 25 Gy and for control plants, respectively. Meanwhile, the value of genetic distance ranged from 0.08 to 0.32.
